Structural Mechanisms of Quasi-2D Perovskites for Next-Generation Photovoltaics

Nano-Micro Letters, Journal Year: 2025, Volume and Issue: 17(1)

Published: Feb. 8, 2025

Quasi-two-dimensional (2D) perovskite embodies characteristics of both three-dimensional (3D) and 2D perovskites, achieving the superior external environment stability structure perovskites alongside high efficiency 3D perovskites. This effect is realized through critical structural modifications in device fabrication. Typically, have an octahedral structure, generally ABX3, where organic ammonium cation (A') participates forming with A'(n) (n = 1 or 2) sandwiched between A(n-1)B(n)X(3n+1) layers. Depending on whether A' a monovalent divalent cation, are classified into Ruddlesden-Popper Dion-Jacobson perovskite, each generating different structures. Although achieves similar effects, they incorporate distinct mechanisms their formation. And according to these structures, various properties appear, additive optimizing methods increase also exist In this review, scientific understanding engineering perspectives quasi-2D investigated, optimal optimization discussed provide insight field.

Efficient Perovskite/Organic Tandem Photovoltaic Devices and Large‐area Modules Featuring Thick‐Film Organic Solar Cells

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 10, 2025

Abstract Perovskite‐organic tandem solar cells (TSCs) possess significant potential due to their unique features, such as orthogonal processing solvents, tunable bandgap, and infinite molecular designs. However, device performance is often hindered by the limited series current density, which constrained absorption of rear organic cell (OSC). Here, a fine‐grained sub‐cell matching model has been developed that enables rapid screening material combinations based on practical parameters. The indicates increasing thickness OSC layer an effective approach boost efficiency, while also reducing manufacturing challenges for large‐scale production. To mitigate charge collection issues arising from excessive thickness, contact passivation technique self‐assembled monolayer developed, minimizes non‐radiative recombination reduces Schottky barrier at interface, enabling more balanced hole‐electron transport. As result, thick‐film (300 nm) achieved record‐high efficiency 18.08% (certified 17.80%), enhancing TSCs 24.31% 24.00%). Furthermore, large‐area photovoltaic module with exceeding 18.54% (18.48 cm 2 ) demonstrated. knowledge, this represents first demonstration perovskite‐organic TSCs.
